Well I don’t think R’ Chaim Brisker spoke such an eloquent English or even English at all. I was quoting his grandson, R’ Yosef Dov Haleivi Soloveitchik, who was saying over what R’ Chaim had said, using his own eloquent English.
He was paraphrasing the tana d’vei rabi yishmael “im pagah b’cha menuval, mashcheihu l’veis hamedrash.”
